The STIHL MS 391 is a robust and powerful petrol chainsaw, ideal for heavy-duty agricultural use and demanding property maintenance. With excellent torque across a wide speed range, it offers plenty of cutting power for harvesting firewood, felling small to medium trees and managing woodland.
 
Starting the MS 391 is made easier thanks to the decompression valve, which reduces the force required on the starter cord and helps protect the starting system. Once running, the 2-MIX engine with four-channel technology ensures efficient fuel combustion, delivering high performance with reduced fuel consumption and exhaust emissions compared to traditional two-stroke engines.
 
The saw is designed with long working hours in mind. The STIHL anti-vibration system uses buffer and spring elements to significantly reduce the transmission of vibrations to the handles, making the tool much more comfortable to use and reducing strain on your hands and arms. The compensator in the carburettor helps to maintain consistent performance over time, even as the air filter becomes dirty, so the saw can run longer between filter cleanings.
 
Maintenance is made easier and more efficient too. The HD2 air filter provides excellent filtration, while the side-mounted chain tensioner allows for quick and safe re-tensioning of the chain. The tool-free fuel and oil caps make refilling fast and straightforward. For lubrication, the MS 391 features the STIHL Ematic chain lubrication system, which ensures oil is delivered precisely where it is needed on the chain and bar, reducing overall oil consumption. The controlled-delivery oil pump also allows you to adjust oil flow depending on your application – increasing it for longer guide bars or very dry wood.
 
The STIHL MS 391 combines reliability, user comfort and strong performance, making it an excellent choice for farmers, landscapers and anyone needing a tough, high-torque chainsaw for demanding jobs.
